Kyoukai Senki episode 20 – A new country?

The whole sub-plot around Yuusei, dear staff, you could now scrap 75% of it except for the autonomous place, even why his parent was dead, and the story will still be 90% the same. The whole “I will do it differently from all of you”, seriously, tell us more! You said because his parent died by fighting Asians, then what kind of missions did they take that resulted in their demise, so much so that their son agree to become their killer’s spy? Guys, you just left it out and let the story continue like it wasn’t something important. Seriously, if they want to do the big reveal then they should have done it sooner, if they even intended to do it in the first place, because at this point, the show is probably gonna end in 5 episodes at maximum. There is no way they can cramp all of it into those finale episodes and say “we did a good job”. Not only Yuusei’s, but Udou’s, Asia’s, and Oceanic’s sub-story have also been reduced too damn much. The oceanic side is the worst case, as the guy that we have in episode 20, Oliver Martin has only appeared in one episode back in the first part, and we hardly have time to actually knew him. Where did that soldier want to attack a town full of Japanese because he got bored? In 8 months, what happened to him? If they manage to fix it in future episodes, I will gladly apologize, but until then, I stand on my ground.
